It is the object of ourpresent invention to provide a system of drivegearing which shall be particularly simple, 'eflicient and compact andwhich shall be related to the frame of the engine so as to be capable ofbeing housed for protection from dust and for lubrication in such a waythatthe frame forms a part of said houslng and the removable cap 1seasyto be got at and does not engage with any bearing or moving part,although aflordlng in combination wlththeframe and bearing castings acomplete and eflicient dust proof casing.

The full objects and advantages of our invention will appear inconnection with the detailed description thereof and are particularlypointed out in the claims. 7

tion of our invention in one form,-Figure 1 is a plan view partly insection of a traction engine embodying our improvements.

Fig. 2 is an elevation of the same portion viewed from the side at thetop of Fig. 1.

As shown in the drawings, and corresponding to the disclosure of theaforesaid application,- a substantially rectangular frame 10 of channeliron is provided, and a ed upon the axle or hub 13. A drawbar 15 issuspended by yoke arms 16 from the frame 10 and is-connected by draftlinks 17 directly with extended portions of the bearing blocks 14 and30. Fast on the hub 13 1 and positioned between the casting portions 31and 33 and the frame members 10 and r 11 is a spur driving gear 18 bywhich the traction wheel-12 is driven. The spur gear 18 meshes with apinion 19 on the short shaft 20 operating in bearings 21 and 22 set intothe casting walls 31 and 33, respec- Y tively. Extending from the endwall 32 of the casting is a portion 23 which provides a bearing for alongitudinaldrive shaft 24 which is operated by a motor andtransmission, not shown, upon the forward part of the frame. The shaft24 has thereon a bevel pinion 25 which meshes with a bevel gear 26 fastwith the pinion 19. The bevel gear 26 extends between casting walls 31and 33 and frame members 10 and 11 shaft 24 is in the same plane as thespur gear 18. It will be apparent that this gearing 1s included in avery narrow space and that aperfectly balanced support upon both In-thedrawings, illustrating the applicalongitudinal frame members 10 and 11is provided. The drive gearing thus compactly positioned is providedwith an exceedingly simple casing which is dust-proof and oil-retainingand embodies the casting walls 31, 32 and 33 and the frame beams 10andll. The lower casing section 27 is bolted or riveted to the lowerflanges of the channel beams 10 and 11. Filler strips 28 and 29 arebolted in position between the channel irons at the ends of the gearspace, as best indicated in Fig. 2, the filler strip 29 cooperating withthe end Wall 32 of the casting to complete the lower part of the casing.A removable cap 34 is provided with a flanged ba e 35 which flanges restupon flanged extesions 36 of the casting 31 throughout the extentthereof and upon the top of the channel beam flanges 10 and 11, theremovable section 34 being bolted alongside of spur gear 18, and thedrive eter and compactly positioned for housing friction. engine is tobe operated in plowing and culinto position by means of these flanges,as indicated. A casing 37 may, if desired, be used to inclose the upperpart of traction wheel 12. It will be seen that by this means anoil-receiving and dust-proof casing for the driving gear is providedwith a readily removable section which does not engage any of the movingor bearing portions of said gearing. The gears 18 and 26 will run in oilwithin this casing and, all dust and dirt being excluded, will operateeasily and with the least possible loss of power from When it isconsidered that our tivating where exposure to sand and dirt isnecessarily very great, the advantage of our dust-proof andoil-containing casing will be apparent. Furthermore, by the use ofoverlapping gears 18 and 26 both of said gears may be made ofcomparativelysmall diamand at the same time the leverage of a singlevery large gear be obtained. The shortness of the shaft 20 with itsdouble bearing and the drive shaft 2& operating in the plane of gear 18transmits the power from said longitudinal drive shaft without anytorsional strain and has the effect of a straight spur gear drivenotwithstanding the employment of the bevel gear 26 overlapping spurgear 18.
